Against dichotomies: on mature care and self-sacrifice in care ethics
Introduction: In previous issues of this journal Carol Gilligan’s original concept of mature care has been conceptualized by several (especially Norwegian) contributors. This has resulted in a dichotomous view of self and other, and of self-care and altruism, in which any form of self-sacrifice is rejected. Although this interpretation of Gilligan seems to be quite persistent in care ethical theory, it does not seem to do justice to either Gilligan’s original work or the tensions experienced in contemporary nursing practice. Discussion: A close reading of Gilligan’s concept of mature care leads to a view that differs radically from any dichotomy of self-care and altruism. Instead of a dichotomous view, a dialectical view on self and other is proposed that builds upon connectedness and might support a care ethical view of nursing that is more consistent with Gilligan’s own critical insights such as relationality and a practice-based ethics. A concrete case taken from nursing practice shows the interconnectedness of professional and personal responsibility. This underpins a multilayered, complex view of self-realization that encompasses sacrifices as well. Conclusion: When mature care is characterized as a practice of a multilayered connectedness, caregivers can be acknowledged for their relational identity and nursing practices can be recognized as multilayered and interconnected. This view is better able to capture the tensions that are related to today’s nursing as a practice, which inevitably includes sacrifices of self. In conclusion, a further discussion on normative conceptualizations of care is proposed that starts with a non-normative scrutiny of caring practices
Healthcare utilization and management of actinic keratosis in primary and secondary care: a complementary database analysis
Background The high prevalence of actinic keratosis (AK) requires the optimal use
of healthcare resources.
Objectives To gain insight in to the healthcare utilization of people with AK in a
population-based cohort, and the management of AK in a primary and secondary
care setting.
Methods A retrospective cohort study using three complementary data sources was conducted to describe the use of care, diagnosis, treatment and follow-up of patients with
AK in the Netherlands. Data sources consisted of a population-based cohort study
(Rotterdam Study), routine general practitioner (GP) records (Integrated Primary Care
Information) and nationwide claims data (DRG Information System).
Results In the population-based cohort (Rotterdam Study), 69% (918 of 1322) of
participants diagnosed with AK during a skin-screening visit had no previous AKrelated visit in their GP record. This proportion was 50% for participants with
extensive AK (i.e. ≥ 10 AKs; n = 270). Cryotherapy was the most used AK treatment by both GPs (78%) and dermatologists (41–56%). Topical agents were the
second most used treatment by dermatologists (13–21%) but were rarely applied
in primary care (2%). During the first AK-related GP visit, 31% (171 of 554) were
referred to a dermatologist, and the likelihood of being referred was comparable
between low- and high-risk patients, which is inconsistent with the Dutch general
practitioner guidelines for ‘suspicious skin lesions’ from 2017. Annually, 40 000
new claims representing 13% of all dermatology claims were labelled as cutaneous
premalignancy. Extensive follow-up rates (56%) in secondary care were registered,
while only 18% received a claim for a subsequent cutaneous malignancy in 5 years.
Conclusions AK management seems to diverge from guidelines in both primary
and secondary care. Underutilization of field treatments, inappropriate treatments
and high referral rates without proper risk stratification in primary care, combined with extensive follow-up in secondary care result in the inefficient use of
healthcare resources and overburdening in secondary care. Efforts directed to better risk differentiation and guideline adherence may prove useful in increasing
the efficiency in AK management
Telomerase promoter mutations in cancer: an emerging molecular biomarker?
João Vinagre, Vasco Pinto and Ricardo Celestino contributed equally to
the manuscript.Cell immortalization has been considered for a long time as a classic hallmark of cancer cells. Besides telomerase reactivation, such immortalization could be due to telomere maintenance through the “alternative mechanism of telomere lengthening” (ALT) but the mechanisms underlying both forms of reactivation remained elusive. Mutations in the coding region of telomerase gene are very rare in the cancer setting, despite being associated with some degenerative diseases. Recently, mutations in telomerase (TERT) gene promoter were found in sporadic and familial melanoma and subsequently in several cancer models, notably in gliomas, thyroid cancer and bladder cancer. The importance of these findings has been reinforced by the association of TERT mutations in some cancer types with tumour aggressiveness and patient survival. In the first part of this review, we summarize the data on the biology of telomeres and telomerase, available methodological approaches and non-neoplastic diseases associated with telomere dysfunction. In the second part, we review the information on telomerase expression and genetic alterations in the most relevant types of cancer (skin, thyroid, bladder and central nervous system) on record, and discuss the value of telomerase as a new biomarker with impact on the prognosis and survival of the patients and as a putative therapeutic target
Integrated genomic characterization of oesophageal carcinoma
Oesophageal cancers are prominent worldwide; however, there are few targeted therapies and survival rates for these cancers remain dismal. Here we performed a comprehensive molecular analysis of 164 carcinomas of the oesophagus derived from Western and Eastern populations. Beyond known histopathological and epidemiologic distinctions, molecular features differentiated oesophageal squamous cell carcinomas from oesophageal adenocarcinomas. Oesophageal squamous cell carcinomas resembled squamous carcinomas of other organs more than they did oesophageal adenocarcinomas. Our analyses identified three molecular subclasses of oesophageal squamous cell carcinomas, but none showed evidence for an aetiological role of human papillomavirus. Squamous cell carcinomas showed frequent genomic amplifications of CCND1 and SOX2 and/or TP63, whereas ERBB2, VEGFA and GATA4 and GATA6 were more commonly amplified in adenocarcinomas. Oesophageal adenocarcinomas strongly resembled the chromosomally unstable variant of gastric adenocarcinoma, suggesting that these cancers could be considered a single disease entity. However, some molecular features, including DNA hypermethylation, occurred disproportionally in oesophageal adenocarcinomas. These data provide a framework to facilitate more rational categorization of these tumours and a foundation for new therapies.ope
